Assignee:

Alcatel Lucent - Paris

International Classification:

H04L 12/28
G06F 15/173

US Classification:

370389, 370392, 37039531, 370412, 709238

Abstract:

A multivariant, common basis classification method and apparatus for classifying protocol data units in a network switching device is disclosed. The method of classifying a protocol data unit (PDU) in the preferred embodiment includes the steps of generating a first string and a second string with which to characterize a PDU; mapping first and second strings into a first index and second index, respectively, where the first and second indices are selected from a plurality of indices; and selecting an instruction to apply to the PDU by matching the first and second indices. The plurality of strings are commonly generated from the source and destination address in the packet as well as other indicia with which to identify a traffic flow. The instructions specify how to classify, route, switch, or otherwise process the PDU.

Appl. No.:

7/735142

Inventors:

Steven R. Clawson - Lakewood CO

Assignee:

Amoco Corporation - Chicago IL

International Classification:

G01V 128

US Classification:

367 38

Abstract:

A method of geophysical exploration is described for transforming qualitative descriptors of seismic data into a quantifiable decision-making tool to estimate the formation properties as well as economic potential of a selected formation in the earth's subsurface. Qualitative descriptors of the waveform of seismic events contained in a first set of seismic signals are obtained and correlated with formation properties to obtain a series of one or more histograms. Qualitative descriptors of seismic events contained in a second set of seismic data can be obtained and transformed into estimates of formation properties as well as estimates of the economic potential of a selected formation for producing hydrocarbons employing such histograms.

International Classification:

G01V 128

US Classification:

367 47

Abstract:

A method of geophysical exploration is provided for identifying and evaluating stratigraphic prospects associated with step-like changes in elastic impedance from gradational changes in elastic impedance. In particular, the seismic data are bandpass filtered with a plurality of filters each having a different pass band. Measures of the amplitude are obtained for selected reflection events in the seismic data as a function of their associated pass band frequency content. The changes in amplitude as a function of changes in frequency content of the reflection event can thus be employed to identify and evaluate subtle stratigraphic prospects in the seismic data.
